From the beginning of this project the RAISE_VARARGS opcode was named and implemented following CPython, where it has an argument (to the opcode) counting how many args the raise takes: raise # 0 args (re-raise previous exception) raise exc # 1 arg raise exc from exc2 # 2 args (chained raise) In the bytecode this operation therefore takes 2 bytes, one for RAISE_VARARGS and one for the number of args. This patch splits this opcode into 3, where each is now a single byte. This reduces bytecode size by 1 byte for each use of raise. Every byte counts! It also has the benefit of reducing code size (on all ports except nanbox). |

This directory contains tests for various functionality areas of MicroPython. To run all stable tests, run "run-tests" script in this directory. Tests of capabilities not supported on all platforms should be written to check for the capability being present. If it is not, the test should merely output 'SKIP' followed by the line terminator, and call sys.exit() to raise SystemExit, instead of attempting to test the missing capability. The testing framework (run-tests in this directory, test_main.c in qemu_arm) recognizes this as a skipped test. There are a few features for which this mechanism cannot be used to condition a test. The run-tests script uses small scripts in the feature_check directory to check whether each such feature is present, and skips the relevant tests if not. When creating new tests, anything that relies on float support should go in the float/ subdirectory. Anything that relies on import x, where x is not a built-in module, should go in the import/ subdirectory.
